It occurs to me that this might be easier and faster if you convert the XML to class instances and only go back to XML at the last minute. Try doing that.

What I want to do is to - 1. Make copy of the XMLListCollection dataprovider in an array by using toArray(); 2. Remove the sort for XMLListCollection dataprovider. 3. Copy the data back from the array into the XMLListCollection. I tried the following(InitiativeList is the XMLListCollection): var iniCopy:Array = InitiativeList.toArray(); var iniXMLCopy:XMLListCollection = new XMLListCollection(); InitiativeList.sort = null; for (var i:int = 0; i < iniCopy.length; i++) { iniXMLCopy.addItemAt(iniCopy[i],i); } InitiativeList = new XMLListCollection(XMLList(iniXMLCopy.toXMLString())); InitiativeList.refresh(); It sort of works but for some reason the first drag I do does not work but then subsequent ones do. Could you give me an idea of where I am going wrong - I guess there is a better way than the long winded method I have used anyway. Thanks a lot.
